If you are ever in a situation where you need to Flash Heal someone, and you are under 50% HP...use Binding heal instead (at least that's how I do it). It'll take getting used to when you first start adding it to the rotation, but once you get it down you'll be able to make the decision between Flash and Binding without hesitation.

I find myself using it daily. As others have stated, Nef P1 (tail lashes) and P2, Chimaeron, or in 5-mans when I get grouped with a not-so-great tank that has threat problems against me or others and there is unnecessary damage taken.

Tonight during our Al'Akir attempts I was using it an average of 10 times just in phase one. It really is a great spell and should be used whenever you and someone else needs a heal. If regen is still a problem you will only want to use it if you both need a heal quickly.

Anytime where I have to heal myself and someone else. It's the most efficient spell we have if you use it correctly.

So pretty much every fight. If you don't use it often, you're playing badly. As said, most efficient spell if it results in no overhealing and it gives you Serendipity. Shorter PoH/GH with reduced mana cost on them.

Whenever I have to heal myself and my lightwell for whatever reason can't do the job. I save my DP for emergencies or if i reckon it's okay to use it cause I won't need it for emergencies. Needless to say I don't use binding heal a lot. But there are few examples where I use it, al akir 10hc p1, to heal myself doing lighthing + tank. Nef hc start of p2, 2x BH into 1x gh is pretty nice.

Other then PvP, during PvE (raids) u should be using anything but binding. You have Light well / DP / CoH / PoH all of which will heal u and ur group for more and faster. 2 of which are instant casts, and have a better HPS then binding.
